The Linux Kernel Is Still On A Power Binge

Phoronix: The Linux Kernel Is Still On A Power Binge

It's been about three weeks since last mentioning the major power consumption problem in the Linux kernel (actually, there's more than one power regression) and it's affecting distributions like Ubuntu 11.04. The lack of mentioning the power regression in recent weeks isn't though because the regressions are addressed, they are still outstanding with the about to be released Linux 2.6.39 kernel...

Seems like an open source/open hardware energy monitoring solution. You can build your own or buy it for 600 to 700$ (yeah, quite expensive). I'm pretty sure it could do what you want by clipping a sensor around the power cable of your computer.

I was looking for the same thing some days ago but still not managed to find a cheap solution to directly log my watt consumption to my computer. All wattmeters either have a small display or log the data BUT you have to transfer it to your pc... (but those wattmeters are cheaper)

Point a webcam at your wattmeter and then ocr the image sequences or video stream
